4-Methoxy-2-methylphenylmagnesium bromide - Introduction
bromide is an organic compound with the chemical formula C9H11BrMgO.
Nature:
bromide is a solid compound, which is a white crystalline powder at room temperature. It has good solubility and is well soluble in organic solvents such as diethyl ether and dimethylformamide. It is a kind of organic magnesium reagent, so it has specific properties in chemical reactions.
Use:
Calcium bromide is an important intermediate for the synthesis of organic compounds. It can be used to synthesize various organic compounds containing methyl and phenyl groups, such as drugs, pesticides and functional materials. It is a common Grignard reagent in organic synthesis and can be used to synthesize olefins, alcohols, ketones and carboxylic acids.
Preparation Method:
The preparation method of the bromide is usually achieved by the Grignard reagent reaction. First, toluene is treated as a nucleophile and then reacted with magnesium bromide to produce 4-tolylmagnesium bromide. Finally, 4-tolylmagnesium bromide was reacted with methyl ether to obtain bromide.
Safety Information:
Because bromide is an organic magnesium reagent, it has high reactivity and corrosiveness. In the use and storage, need to follow the corresponding safety procedures and measures. It should be kept away from fire and oxygen, avoid contact with skin, eyes and respiratory tract. Appropriate personal protective equipment should be worn during operation to ensure safety.
